Values corresponding to <code>errno</code> codes returned from file operations on UNIX.
<p>
Unlike <code>errno</code> codes, <a class="el" href="classGlib_1_1FileError.html#s24">FileError::Code</a> values are available on all systems, even Windows. The exact meaning of each code depends on what sort of file operation you were performing; the UNIX documentation gives more details. The following error code descriptions come from the GNU C Library manual, and are under the copyright of that manual.
<p>
It's not very portable to make detailed assumptions about exactly which errors will be returned from a given operation. Some errors don't occur on some systems, etc., sometimes there are subtle differences in when a system will report a given error, etc. <dl compact><dt><b>Enumeration values: </b></dt><dd>

</td></tr>
<tr><td valign=top><em><a name="s24s6" doxytag="NO_SUCH_DEVICE"></a><em>NO_SUCH_DEVICE</em></em> </td><td>
<code>(ENXIO)</code> No such device or address. The system tried to use the device represented by a file you specified, and it couldn't find the device. This can mean that the device file was installed incorrectly, or that the physical device is missing or not correctly attached to the computer. <br>
<br>

<br>
</td></tr>
<tr><td valign=top><em><a name="s24s17" doxytag="INVALID_ARGUMENT"></a><em>INVALID_ARGUMENT</em></em> </td><td>
<code>(EINVAL)</code> Invalid argument. This is used to indicate various kinds of problems with passing the wrong argument to a library function. <br>
<br>
</td></tr>
<tr><td valign=top><em><a name="s24s18" doxytag="BROKEN_PIPE"></a><em>BROKEN_PIPE</em></em> </td><td>
<code>(EPIPE)</code> Broken pipe; there is no process reading from the other end of a pipe. Every library function that returns this error code also generates a <code>SIGPIPE</code> signal; this signal terminates the program if not handled or blocked. Thus, your program will never actually see this code unless it has handled or blocked <code>SIGPIPE</code>. <br>
<br>
</td></tr>
<tr><td valign=top><em><a name="s24s19" doxytag="TRYAGAIN"></a><em>TRYAGAIN</em></em> </td><td>
<code>(EAGAIN)</code> Resource temporarily unavailable; the call might work if you try again later. We used TRYAGAIN instead of TRY_AGAIN, because that is a defined as a macro by a Unix header. <br>

<tr><td valign=top><em><a name="s24s20" doxytag="INTERRUPTED"></a><em>INTERRUPTED</em></em> </td><td>
<code>(EINTR)</code> Interrupted function call; an asynchronous signal occurred and prevented completion of the call. When this happens, you should try the call again. <br>
<br>
</td></tr>
<tr><td valign=top><em><a name="s24s21" doxytag="IO_ERROR"></a><em>IO_ERROR</em></em> </td><td>
<code>(EIO)</code> Input/output error; usually used for physical read or write errors. I.e. the disk or other physical device hardware is returning errors. <br>

Does not correspond to a UNIX error code; this is the standard "failed for unspecified reason" error code present in all <a class="el" href="classGlib_1_1Error.html">Glib::Error</a> error code enumerations. Returned if no specific code applies. </td></tr>
